Here is an example of how to add an image to an existing report, saving it in the internal storage and keeping the path in the database. E:DevelopersAndroidandroid-sdk-windowstools> adb shell. I recommend you save the pictures to the internal storage since so it’s accessible only from your application and is available at all times actually, the SQLite database itself is also stored in the internal storage. Similar to how extras stores data, an instance of ContentValues stores data as key-value pairs, where the key is the name of the column and the value is the.

These capabilities can be leveraged by using the Database manager in the Core module. Android provides developers with a powerful and lightweight relational database management system called SQLite. Android apps can only store data in a SQLite Database. For example, if you’re storing reports about observations the users make in the field that will be uploaded to the main system later, it can be handy to add a picture to better describe the problem. The database handler will be a subclass of SQLiteOpenHelper and will provide an abstract layer between the underlying SQLite database and the activity class.
